Class of Service

Classification based on outer IP DiffServ code point (DSCP) for the de-encapsulation tunnel interface (PTX10001-36MR and PTX10008)—By default, when a packet exits a tunnel, the terminating router removes the tunnel (outer) header and forwards the packet based on the classification in the inner header. Starting in Junos OS Evolved Release 23.2R1, on PTX10001-36MR and PTX10008 routers that act as an egress router for a tunnel, you can forward the packet based on the classification you assign to the outer header at the underlay (ingress) interface. To use this feature, you first set the no-default option at the [edit class-of-service interfaces ftin unit 0 classifiers] hierarchy level. You then assign the desired classifier to the underlay interface.
